3.2 also test according to method above the medicine of all the other embodiment, result shows, the mass ratio of epoxiconazole and carbendazim is when 1-80:1-80, to the control efficiency of bitter rot or anthracnose of grape more than 88%, the mass ratio of carbendazim and epoxiconazole is in 1:1~4 o'clock, gained bactericidal composition effect is between 93%, and the mass ratio of carbendazim and epoxiconazole is when 1:2.2, and gained bactericidal composition effect is more than 97%.
4 sum up
The preferred compositions of the preferred and auxiliary agent of bactericidal composition effective ingredient consumption of the present invention, microbicide compositions drug effect the best of gained.The mass ratio of carbendazim and epoxiconazole is that 1:1~4 o'clock bactericidal effect is fine, and when mass ratio is 1:2.2, effect is best, and the bactericidal composition effect that exceeds this scope decreases.By data, can learn, the combination of epoxiconazole of the present invention and kresoxim-methyl has improved the sick control efficiency of bitter rot or anthracnose of grape, has reduced usage amount and the access times of medicine, economical and practical, and effectively reduces ecosystem environment and pollute, and can improve crop yield and quality.
